Town located in the lower part of the Lazio region, in the province of Frosinone, washed by the rivers Liri and Sacco, Ceprano was a colony founded by the Romans in 328 B.C., and named "Fregellae".
In 1994, during an excavation, the important discovery of "homo Argil", probably the oldest in Europe, attest that the area was already inhabited since more ancient times. The current name probably honors the name of the important family Ceparia.
Due to its favorable geographic location along some of the most important ancient trade routes, on the border between the Kingdom of the Two Sicilies and the Papal States, Ceprano was often raided and looted by the Goths of Totila, and later by the Saracens. Here Gregory VII assigned to Robert the Guiscard, the throne of Apulia and always here, in 1230, Emperor Federico II was acquitted of excommunication and later, king Manfredi swore allegiance to Innocent IV - suffering the humiliation of crossing the entire bridge of the Liri, holding the reins of the horse of the Pope, while, a few centuries later, the troops of Joachim Murat were defeated by the Austrian ones.
